The height of the scale beam is adjusted by the user to match the thickness of the sample. The tool, a conical diamond tip, is then placed on the sample and the instrument is activated by the user with the On / Off switch.
The tip leaves a trace mark and the extent of this, in relation to the load used, indicates the degree of coating or material hardness. The turntable rotates at a constant 5rpm to ensure repeatability and reproducibility of tests. By changing the load on the tool, from 0 – 1000g, the sample’s scratch resistance can be evaluated.
Sample Cutter: The Sample Cutter cuts precise 106mm circular samples with a 6.35mm centre hole to prepare specimens for use with the Taber® Abrasers.
An easy counter-clockwise cutting motion allows the user to cut a variety of materials. Optional pads allowing cutting thicknesses of 0.03mm, 4.74mm and 6.35mm are available.
